+1 Anyone stating a coin here should defend the items above for this coin IMO...

I believe the major criteria for the sustainability of a coin is a stable value so that it will be widely adopted by merchants.

Darkcoin is one of the best coins there is from a technical standpoint. It's only problem is that it's name and function may prohibit it to a small market cap labeled as a drug dealer coin or something.

That same quality might also elevate it to high market cap by the same users. After all, Satoshi didn't invent Bitcoin. Bitcoin was useless. Ross Ulbricht invented Bitcoin.

Also, I'm not sure if people have rocks for brains in these threads because I rarely see anyone ever talking about economic models. Many coins have identical models, some are a lot different. Cashcoin probably has the best economic model I've seen on a coin so far. If anyone thinks there's a better one, name it, because I haven't seen it.

No, I don't consider Freicoin viable, because people have the freedom to choose something that will give them more profit, so why bother with that?

Quark and NXT shills get the fuck out. Everyone is tired of reading your forum spam. You will rarely see someone with high post count shilling for these coins. It's always some 1 star poster paid to type this crap from Nigeria.

This is a waste of a post. People are going to "talk their book". By pure metrics LTC has the most utility in that next to BTC it is most accepted my merchants for transactions (not exchanges). The next is FTC and then it falls off a cliff.
